Forensic Intern

Lu Wang pulled Tong Yu up to the second-floor rooftop: "There is no one else here, so explain what you just said clearly, who is the culprit, and what does it mean?"

The wind on the roof was blowing on his forehead, which made Tong Yu calm down a little. He took out the last cigarette from his pocket and lit it, took a deep breath, and exhaled a faint wisp of smoke: "Su Da's phone number is for me. Lin Xiaoxiao's."

"So, what does a call mean?" Lu Wang really didn't understand what the disappearance of the two people had to do with the phone number.

Tong Yu: "On the first day of school, Lin Xiaoxiao recruited new students for the cosplay club and stopped me."

Lu Wang: "Well...and then?"

Tong Yu: "Then I wrote down Su Da's phone number."

Lu Wang: "That's no problem, I've done this kind of thing before."

Tong Yu: "But later Lin Xiaoxiao added Su Da's WeChat."

Hearing this, Lu Wang scratched the back of his head: "You mean, Lin Xiaoxiao regards you as Su Da? She doesn't think she has a crush on you, does she?"

Tong Yu pondered for a moment: "If I remember correctly, I registered Su Da's phone number in the notebook in the morning, and Lin Xiaoxiao added Su Da's WeChat at noon. This should not be a coincidence."

"So... Lin Xiaoxiao always thought he was chatting with you when he was chatting with Su Da?" Lu Wang finally understood the relationship between these three people.

"It should be like this. I wasn't sure at the beginning. After seeing Lin Xiaoxiao and Su Da have a dispute, I guess it might be so."

The smoke lingered between the two, and Tong Yu looked in a bad mood: "So it's my fault."

Lu Wang thought for a while, then turned the cigarette in the opponent's hand, and pinched it between his fingertips. He took a deep breath of the mint-flavored cigarette, which moistened his throat and said, "You are the theory of cause and effect. Well, I don't think you can think like that."

Tong Yu: "Then what should I think?"

Lu Wang put a hand on Tong Yu's shoulder, and began to analyze with him seriously: "First, Lin Xiaoxiao took the initiative to add WeChat, and you didn't force her; second, the two didn't know each other clearly before dating, It's their problem; third, they had a dispute because of poor communication, and it has nothing to do with you!"

Tong Yu raised his eyes, looked at Lu Wang, and found that this guy's logical thinking was quite clear.

He did have some theory of cause and effect, but when he thought of the phone call that he didn't get through in time, regret would jump out to replace reason.

If the phone was connected, maybe Mom wouldn't have died... If he hadn't left Suda's phone number, the two wouldn't have disappeared...

"What are you thinking?" Lu Wang saw that the other party was absent-minded, so he squeezed Tong Yu's shoulder to pull his thoughts back: "Did you hear me?"

"I'm not deaf." Tong Yu's eyes were already red, but his tone of voice remained the same.

Seeing Tong Yu's appearance, Lu's heart softened instantly, and his eyebrows furrowed together in an extremely rare way: "The situation this time is different from the previous few times. The scope of the murderer has been narrowed down a lot, and Su Da's phone number It can still be connected, and the police have already searched for the location."

Tong Yu lowered his eyes and did not speak, but the emotions visible to the naked eye have become much more stable, and it seems that he has listened to his words.

Lu Wang pushed back the crooked hair on the other side's forehead: "Don't think too much, listen to the captain's arrangement later, maybe we can help."

Tong Yu was about to say: Take your hoof off.Before he could say anything, Lu Wang's phone vibrated twice, and the finger that landed on his forehead suddenly changed direction.

Lu Wang picked up the phone and glanced at it: "Teacher Gu asked us to go back to the meeting."

After finishing speaking, he put his mobile phone in his pocket, raised his arms around Tong Yu's neck, and whispered in his ear: "I find you are a little sentimental, why are you bitching!"

If Lu Wang hadn't run fast, Tong Yu might have thrown him over the shoulder on the spot!

When the two returned to the conference room, the backbones of each department were already in place, and everyone had serious expressions on their faces.

Zheng Ju sat at the main seat in the conference room, with a square face, the bags under the eyes and nasolabial folds looked deep, and there was a thermos cup in his hand, emitting white smoke.

Mo Lin, an expert in criminal psychology, has been on frequent business trips for the past few days. When he was on the plane, he had already read the latest information on the case.

His voice came out of the microphone, low and elegant: "I read the files you handed over, and my thoughts are the same as everyone else's. The murders are indeed from the same murderer..."

Mo Lin was dressed in a casual suit, and looked very approachable, without any airs of an expert.

Since he had to catch up with the next video conference in a while, he glanced at the beating mechanical watch in his hand, intending to seize the time to explain.

Everyone present became quiet, even Director Zheng put down his mobile phone, folded his hands on the table, and listened carefully to the other party's speech.

Lu Wang glanced at Mo Lin who was sitting next to Director Zheng, turned his head and said to Tong Yu, "This is the first time I saw Teacher Mo in person, he is much more handsome than I saw on TV, look at Captain Wang's face Looks like a little fanboy..."

Tong Yu followed Lu Wang's line of sight, and saw that Captain Wang was sitting next to Teacher Mo, taking notes meticulously, with his back sitting upright, and every time Teacher Mo said a word, he had to write a few words in the notebook.

Mo Lin recalled the whole process of the case: "The death method and process of the suitcase female corpse, the Linhu female corpse, and the construction site female corpse are basically the same. The autopsy report of the forensic doctor has written very clearly, so I won't go into details. The psychological activities of the murderer, to help everyone understand the process of the psychological evolution of the murderer..."

Speaking of this, Tong Yu sat up straight. He had already read the textbooks and made a criminal portrait profile of the murderer, but after all, his knowledge was limited, so he could only draw a superficial profile.

Since the appearance of the totem, he can no longer connect the whole case together. Now the most authoritative criminal psychology expert in the country is sitting opposite, and he is in awe.

"Everyone here knows that the murderer's target is women with obvious secondary sexual characteristics, and there is no direct relationship between the murderer and the victim. His killing is completely random."

All the faces in the audience were serious, especially Li Meng, his fists clenched when he heard the word "randomly selected". The criminal he hated the most was a rapist, not to mention that this rapist also killed people!

Mo Lin: "During the killing process, the murderer showed obvious signs of venting his anger. The murderer mainly took pleasure in humiliating women. After killing women, he cut off her right breast to vent his sexual desire... .

From the perspective of personality development, the murderer is very likely to have received improper sex education when he was young, so that the murderer suppressed his sexual desire for a long time and had a wrong perception of the opposite sex.

This kind of sex education most likely comes from the murderer's mother. As the backbone of the family, the mother has a lot of weight in her words, and she has given "excessive purity" education to the murderer in her boyhood. This situation is common in single-parent families.

In the murderer's cognition, women are both sacred and the source of his pain, just like his mother, who raised him selflessly while controlling him ideologically, making him struggle for a long time on the verge of mental breakdown.

The murderer longs for the female body, and once the years of repression and restriction are broken, the desire will be released in multiples.For example: the mother's death, family changes, these reasons may cause the murderer to no longer be controlled by the mother, thus generating the motive of killing under the abnormal psychology.

Because the murderer couldn't get the ideal balance on the opposite sex, he turned himself into a demon to punish the women who tortured him, put his anger on strange women, and killed them to obtain release and relief. When he kills a person, he feels that his power has become stronger, and from this, he thinks that he can dominate women.

This kind of pleasure can temporarily alleviate the imbalance and contradiction in his heart, but this pleasure decays too fast, he desperately wants to gain more dominance, so he kills the second person, the third person...

Gradually, he became obsessed with dominance and began to seek more ways to obtain this power. He wanted to rely on totems and sacrifices to obtain external power, so he became obsessed with witchcraft and began to study ancient classics.

Bookstores and libraries are very likely to show his presence, and the borrowed books cover a lot of ancient witchcraft.

After the female corpse at the construction site, he began to try to use totems and sacrifices to gain external power. That is to say, since August, he began to study witchcraft, so you can go to the library to check the borrowing records of books in this area, focusing on On the content of the sacrifice. "

Tong Yu listened very carefully, and could directly infer the murderer's childhood growth experience and family environment from the murderer's criminal behavior, which showed that Teacher Mo's research on criminal psychology was not limited to assisting the police in handling cases.

He is actually studying the criminal's psychological activities, as if in his eyes, the criminal is also a human being, and he does not analyze a murderer with colored glasses.

This is probably the reason why Teacher Mo is strong in the professional field!How lucky it would be to be able to worship such a teacher as a teacher!

Lu Wang noticed that Tong Yu was in a daze, and poked his elbow: "What are you thinking? I can't even roll my eyes when I stare at Teacher Mo!"

Tong Yu came back to his senses: "It's nothing, I just think he is very powerful."

"It's rare to see you praise others, so praise me anytime!"

"You are dreaming, why should I praise a fool?"

Lu Wang felt a little frustrated in his heart: "Okay, don't call an idiot to drive you back to school in the future!"

Tong Yu: "I thought you were used to being called a fool."

Lu Wang: "Can the fuck get used to this?! Tong Yu...you are really a dog!"

After analyzing the murderer's psychological activities, Mo Lin looked at Wang Yue: "I want to hear what your criminal investigation team thinks."

Wang Yue turned on the microphone in front of him: "Let me just say something briefly... Judging from the location of the burial on the construction site, the murderer should be located in the south of Qingxiu District, and have a vehicle that is convenient for kidnapping and throwing the body.

Everyone has seen the videos distributed on the Internet. Even the police cannot trace the ID address of the video release, which proves that the murderer has a good understanding of electronic information technology, or has high professional skills, and is likely to be engaged in this field. The residence may be equipped with many advanced Electronic devices such as surveillance, bugs, and even signal jammers.

But Su Da's phone can still be connected so far, I hope it is not a trap... Just to be on the safe side, we have already notified the brother who tracked the mobile phone signal, and be careful when approaching to prevent fraud. "

Director Zheng nodded, expressing his approval of Wang Yue's approach.

After Wang Yue finished speaking, he looked at Gu Yuan: "Do you have anything to add to the Forensic Medicine Department and the Physical Evidence Department?"

Yan Ji turned on the microphone, with a helpless expression on his face: "The Evidence Division has collected limited evidence, the murderer has a strong sense of anti-reconnaissance, the modus operandi is clean, and no fingerprint information is left.

We found talcum powder on the rubber gloves on the clothes of the deceased, presuming that the murderer was wearing medical rubber gloves. In addition, the plastic wrap on the body of the woman in the suitcase looked clean, except for the fibers inside the suitcase, almost There was no other dust, and it was certain that the place where the corpse was wrapped should be in a clean room.

The registration information of the diamond ring is still under investigation. I have already contacted dr's headquarters company. They will send us the list of registrants for this ring as soon as possible. We only have these for the time being. "

After Yan Ji finished his report, Gu Yuan turned on the microphone in front of him. His voice sounded crisp and almost without any emotional fluctuations: "Based on the previous autopsy reports, the murderer's tool has been determined: cutting The tool used for the breast is a single-edged sharp tool with a length less than 10cm. The tool used for cutting fingers is a chainsaw. Judging from the cutting arc, it should be a small chainsaw. This kind of thing is easy to buy in the market. The rope of the dead is also common, a double twisted rope."

"As for the female corpse in the suitcase, I would like to add something." Gu Yuan said while playing the photos on the projector when the corpse was found: "There are a lot of drops of water on the plastic wrap wrapped on the corpse, and there is also water inside the suitcase, but the outside Drying, combined with the autopsy, it can be speculated that the deceased was frozen after death."

This detail made the people present stand in awe, Gu Yuan continued: "Within two hours after the death of the deceased, the murderer wrapped the body in plastic wrap in all directions, and put it into the suitcase in a curled up form.

After a period of time, rigor began to occur. The murderer did not directly discard the corpse and the suitcase, but dragged the corpse out of the suitcase after the rigor and plaques formed, so I speculate that the murderer used To a large freezer.

As for why the body was taken out of the suitcase, I think that the murderer may have encountered some special circumstances at the time, so that he did not throw the body in time. After that, the murderer directly threw the suitcase beside the trash can, looking very hasty. Some accident may have happened. "

"Let me interrupt." Wang Yue raised his hand and said, "The order of death of the deceased is: the corpse of the suitcase woman - the corpse of the Linhu woman - the corpse of the construction site woman, and the stumps found in the unfinished building. The corpse of the suitcase woman did not use transportation, and the corpse of Linhu The female corpse used transportation, the female corpse on the construction site used transportation, and the stump did not use transportation... Is it possible to infer that the vehicle used by the murderer to throw the corpse may have broken down, and the failure happened twice?"

Gu Yuan: "I don't think there is a way to deduce for the time being whether the stump of the unfinished building used transportation."

Wang Yue: "If there is transportation, the murderer doesn't need to dismember the body before throwing it away. For an adult female body over 160cm tall, if there is no means of throwing the body, the murderer should think of dismembering the body."

"I agree with the statement that there was a breakdown in the vehicle." Mo Lin interjected, "But the murderer's intention to dismember the body is still unclear. After all, no other body parts have been found so far. I think this speculation can be kept temporarily."

Wang Yue thought for a while, and felt that what Mo Lin said made sense: "Teacher Gu, you continue."

Gu Yuan lowered his head and opened the inspection report on the desktop: "The inspection report of the female corpse at the construction site has come out. Treponema pallidum was detected in the vaginal scrapings of the deceased. Our previous speculation is true. The murderer is currently carrying treponema pallidum, and it has already appeared. Urinary tract infection."

"Combining the murderer's current mental state..." Mo Lin added: "The murderer should be in the stage of desperately wanting to become stronger. He will think that his weakness is caused by the decay of strength. In this way, he should speed up The speed of crime."

Director Zheng said in a deep voice: "At present, the scope of the murderer's activities has been reduced to a very small one. I have already contacted the police to assist us in handling the case, and conducted a blanket search of the area south of Qingxiu District.

Although the surveillance captured the murderer's height and body shape, the murderer was wearing a mask, which was too common for the police to investigate. Therefore, the forensic doctor and Mr. Mo were asked to give a more detailed profile of the criminal portrait. "

Mo Lin turned the black paint pen in his hand: "The murderer is a male, aged between 20 and 30 years old, about 175 to 178cm tall, thin, unmarried, living alone, with good living conditions, introverted, unsociable, proficient Electronic information technology, may be engaged in related work."

Gu Yuan added: "Judging from the semen test report, the murderer's sperm was of poor quality and thin concentration, which is a typical manifestation of excessive indulgence. People in this state will show a depressed state of mind. , accompanied by drowsiness, sweating, insomnia and dreaminess, disordered work and rest..."

Hearing this, Lu Wang sighed with emotion: "Mr. Gu's analysis is too careful!"

Tong Yu: "What's the matter? Doctors in ancient times could guess what you ate tonight by tasting your stool."

Lu Wang: "Hey, can you stop being so disgusting? Are you going to eat tonight?"

Tong Yu: "During the autopsy, I didn't see that you couldn't eat. Why are you being pretentious?"

Lu Wang could see that when Tong Yu was in a bad mood, what he said would be thorny, but if it was someone else, he would have done it long ago.

Lu Wang: "Can it be the same? It's shit!"

Tongyu: ...

Tong Yu held back for a while but still didn't hold back. Neither the corpse nor the stool made him sick. The word "shitbaba" really made him a little sick. He frowned and said to Lu Wang: "Can you stop talking about double words in the future?" ?”
